Paragangliomas or extra-adrenal pheochromocytomas account for approximately 15% of all pheochromocytomas. They are usually found in an intradiaphragmatic location. Paragangliomas of the urinary bladder are infrequent and represent 6% of the paragangliomas and 0.06% of all bladder tumors. We describe 2 cases of urinary bladder paragangliomas attended to our center and review the literature with special attention to treatment, since there is some controversy around the management of these tumors. Surgical options include partial or total cystectomy and transurethral resection, but there is no consensus regarding these treatment modalities. The 2 patients presented underwent transurethral resection with a good outcome and no recurrence or residual disease.
